2 >
3 > 1. IBExtract: Identity columns - add addition check for null column for generator name.
4 >
5 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
6 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
7 >   information). Values returned as a result of executing an Insert or Update statement
8 >   replace existing values in the current row for each corresponding column.
9 >
10 > 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
11 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
12 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
13 >   each Identity column after the insert is executed.
14 >
15 > 4. TIBGenerator: small performance improvement by not preparing query each time
16 >   a new number is generated.
17 >
18 > 5. TIBSQL: Free resources when transaction changed.
19 >
20 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
21 >
22 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
23 >   changes.
24 >
25 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
26 >   Bug could result in truncated multi-byte character set values.
27 >
28 > 3. Changes consequential on moving fbintf character set utility functions from
29 >   IFirebirdAPI to IAttachment.
30 >
31 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
32 >
33 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
34 >   results in autocomplete ignoring prefix text.
35 >
36 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
37 >   entering a new name into the text box.
38 >
39 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
40 >   Firebird rather than recomputing it.
41 >
42 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
43 >   screen centre. Previously some were "poDesigned" which may be inappropriate
44 >   for multi monitor desktops.
45 >
46 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
47 >
48 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
49 >    a transaction and always reset the object.
50 >
51 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
52 >
53 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
54 >
55 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
56 >    to a gbak format archive.
57 >
58 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
59 >
60 > 16. IBLocaldb: Drop database if error creating an empty database.
61 >
62 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
63 >    unless selected node not in current dataset.
64 >
65 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
66 >    to TIBCustomService, and IBlocalDB code tidy up.
67 >
68 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
69 >    behaviour due to uninitialised variable.
70 >
71 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
72 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
73 >
74 > 21. IBSQL: When Database changed ensure that all resources are freed.
75 >
76 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
77 >
78 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
79 >    * Line Wrap on SQL Token boundaries (on user command)
80 >    * auto-complete table names in drop down list of table names
81 >    * Double click on tablename or field name adds to SQL text
82 >
83 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
84 >
85 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
86 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
87 >    workaround for a problem in fpc 3.0.4 win64).
88 >
89 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
90 >
91 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
92 >
93 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
94 >
95 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
96 >   include remote system name.
97 >
98 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
99 >   tables when data included in output.
100 >
101 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
102 >   and timing information to be written to stdout. This may be used to locate
103 >   performance bottlenecks.
104 >
105 > 4. SQLParser: only call "OnChanging" event handler when value is different.
106 >
107 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
108 >
109 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
110 >   that BindFields is called when the query is next activated. Avoids FieldName
111 >   not found error.
112 >
113 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
114 >   purpose and allows the programmer to define any action they want for Update, Insert
115 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
116 >   filtering of updates, or use of statements such as Grant or Revoke instead of
117 >   normal DML. See User Manual for more information.
118 >
119 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
120 >
121 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
122 >
123 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
124 >
125 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
126 >   hexadecimal notation.
127 >
128 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
129 >   using a simple XML format.
130 >
131 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
132 >   grants to these objects.
133 >
134 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
135 >   dependency problems restoring complex databases.
136 >
137 > 7. TIBXScript: This component has been restructured to allow for the processing of
138 >   embedded XML in INSERT statements and to support interactive sources in addition
139 >   to non-interactive data sources such as files.
140 >
141 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
142 >
143 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
144 >   SET SQL DIALECT
145 >   SET TERM
146 >   SET AUTODDL
147 >   SET BAIL
148 >   SET ECHO
149 >   SET COUNT
150 >   SET STATS
151 >   SET NAMES <character set>
152 >
153 > 10. IBVersion unit added to hold current IBX Version Number information.
154 >
155 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
156 >    and domain definitions.
157 >
158 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
159 >    fully supported.
160 >
161 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
162 >
163 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
164 >
165 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
166 >
167 > See also doc/IBX4LazarusGuide.pdf for important information on
168 > upgrading to IBX2.
169 >
170 > 1. Size property of TIBStringField is now the width in characters of the field
171 >   and not the byte length. This applies only to multi-byte character sets such
172 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
173 >   code is not recognised as a bug and hence this change to align the behaviour.
174 >   The TStringField change is expected in fpc 3.2.0.
175 >
176 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
177 >   true (default) then Size property value saved in the lfm is ignored. Size is
178 >   always set from the dynamic information read from the database. It is unclear
179 >   why anyone would want to override this and set Size to false.
180 >
181 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
182 >   block.
183 >
184 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
185 >   exist when an attempt is made to connect to it (run time only) then an attempt
186 >   is made to create the database.
187 >
188 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
189 >   has been successfully created as a result of a call to CreateDatabase or when
190 >   creating a database after it was found not to exist.
191 >
192 > 6.  DBControlGrid: a race condition could result in the wrong row image being
193 >    written to the cache. This has been avoided by a trip round the message
194 >    loop before rendering the row image.
195 >
196 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
197 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
198 >    known to risk corrupt rendering of row images when the control is first
199 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
200 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
201 >
202 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
203 >    a TDateEdit control located on an editor panel.
204 >
205 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
206 >
207 > 10. DBControlGrid: Removed memory leak when updating rows.
208 >
209 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
210 >
211 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
212 >
213 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
214 >   when target codepage is CP_NONE. This is a workaround for
215 >   http://bugs.freepascal.org/view.php?id=30622.
216 >
217 > 2. DBLog option removed from TIBStatisticalService - not supported by server
218 >   since Firebird 1.5.
219 >
220 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
221 >   similar.
222 >
223 > 4. IBCodePage: updated mapping between codepages and character id.
224 >
225 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
226 >   Firebird. Character sets with a char width of two are not UTF16.
227 >
228 > 6. Strings received from the database are now always transliterated into UTF8
229 >   regardless of the database character set or connection character set. This
230 >   is for compatibility with the LCL.
231 >
232 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
233 >
234 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
235 >   read in an entire blob just to get the size of the blob. General performance
236 >   improvement when opening datasets containing blobs.
237 >
238 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
239 >
240 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
241 >   is now used.
242 >
243 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
244 >   determined.
245 >
246 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
247 >
248 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
249 >   lazarus 1.6.0
250 >
251 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
252 >   compilation error.
253 >
254 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
255 >
256 > 1. No character set specified for connection: when a text blob is retrieved, the
257 >  character set is determined by looking up the native character set using then
258 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
259 >  set as the connection.
260 >
261 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
262 >   for Login Dialog returing a change to the database path.
263 >
264 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
265 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
266 >   entered value to be saved on a project specific basis (design time only).
267 >
268 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
269 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
270 >   Otherwise, it sets the column text to the selected ListField Value.
271 >
272 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
273 >   column width.
274 >
275 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
276 >   and a case insensitive search is requested.
277 >
278 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
279 >   or column ListSource.
280 >
281 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
282 >   unprepare) when closing and the text has not changed.
283 >
284 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
285 >   Less likely to cause a cursor re-use error on Windows.
286 >
287 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
288 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
289 >
290 > 11. TIBTreeView: Guard against nil destination on record changed
291 >
292 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
293 >    string type with the code page set to reflect the returned field encoding after
294 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
295 >    earlier versions.
296 >
297 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
298 >    will now result in transliteration to the code page specified for the Firebird driver
299 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
300 >
301 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
302 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
303 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
304 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
305 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
306 >    the GETACP is used to determine the Windows code page.
307 >
308 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
309 >    name used as the lc_ctype when the database was opened. Only valid while the
310 >    Database is connected.
311 >
312 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
313 >    id that corresponds to the DefaultCharSetName.
314 >
315 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
316 >
317 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
318 >   path is given and database attach fails due to access permission issues on the
319 >   temp directory or security database, then the attach is retried with "localhost:"
320 >   prefixing the databasename. This should avoid problems when the database has to
321 >   be accessed by a local (e.g. classic) server and libfbembed is used.
322 >
323 > 2. Windows: revised search order for Firebird DLL:
324 >     i.   The Firebird Embedded Server in the application Directory.
325 >     ii.  If the FIREBIRD environment variable is set then the directory this
326 >          points to is searched for the FB Client DLL and then then underlying
327 >          "bin" directory.
328 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
329 >          is used to locate the Firebird installation directory and the underlying
330 >          "bin" directory is searched for the FB Client DLL.
331 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
332 >          are searched for the FB Client DLL.
333 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
334 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
335 >
336 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
337 >   See doc/readme.scriptengine and example applications.
338 >
339 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
340 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
341 >   See dpc/readme.localdatabase and example applications.
342 >
343 > 5. IBDynamicGrid: Reordering on column header click should now also work for
344 >   dynamic columns.
345 >
346 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
347 >   between incrementing/decrementing the lock count and signalling the event.
348 >
349 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
350 >
351 > 1.3.2 was never formally released and only made available as beta copies.
352 >
353 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
354 >
355 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
356 >
357 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
358 >
359 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
360 >   i.e. when it is a calculated field
361 >
362 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
363 >   This problem was due to a race condition between recalculating row heights and
364 >   determining which row was selected by the mouse click. The row height calculation
365 >   is now deferred by an extra trip round the message loop allowing the row to
366 >   be always calculated on the current grid layout rather than risking it being
367 >   calculated on the grid layout after the expanded row has been shrunk.
368 >
369 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
370 >   Windows.
371 >
372 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
373 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
374 >   to be determined at runtime. See doc/readme.charactersets.html.
375 >
376 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
377 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
378 >
379 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
380 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
381 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
382 >
383 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
384 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
385 >   implies no truncation.
386 >
387 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
388 >
389 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
390 >   (avoids "Not in Edit Mode" error).
391 >
392 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
393 >
394 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
395 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
396 >
397 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
398 >
399 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
400 >
401 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
402 >
403 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
404 >
405 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
406 >
407 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
408 >
409 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
410 >     problem with row size when exception is called.
411 >
412 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
413 >
414 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
415 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
416 >
417 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
418 >     keyed in i.e. when autocomplete not performed
419 >
420 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support

509 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
510 >    and "AfterExecQuery". The first three are called after the same event is called
511 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
512 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
513 >    enable monitoring of transaction status changes for a given transaction to be
514 >    handled in a single place. For example, when a change to the dataset occurs
515 >    an indicator can be set that shows the user that in order to save changes,
516 >    the transaction should be committed.  Rather than doing this per dataset, this
517 >    can now be done per transaction.

519 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
520 >    the dataset is scrolled. However, any changes to the current row are, by default,
521 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
522 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
523 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
524 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
525 >    then IBX will attempt to post any unsaved changes before the dataset is closed
526 >    (and after the BeforeClose event handler is called). The exception is when the
527 >    dataset is being closed as a result of a transaction rollback. In this case,
528 >    no action is taken and any unsaved  changes are discarded. This avoids both
529 >    unnecessary overhead and the risk that a validation error may occur in the Post
530 >    raising an exception and thereby preventing a rollback.
531 >
532 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
533 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
534 >    width. Display Widths are now corrected by dividing by the max byte width per character.
535 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
536 >    the byte width divided by 4. The byte width of each character set is determined
537 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
538 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
539 >
540 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
541 >
542 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
543 >    control loses focus. Default Key press default interval reduced to 200ms.
544 >
545 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
546 >    when dataset rows are less than visible rows.
547 >
548 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
549 >    does not exist or DataSet is empty. More responsive on dataset open. New event
550 >    OnRestorePosition. Column sort disabled if no header row.
551 >
552 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
553 >    while dataset state is dsInsert. Avoids posting errors.
554 >
555 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
556 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
557 >
558 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
559 >
560 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
561 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
562 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
563 >    always "posts" the current record regardless or whether or not it may be more appropriate
564 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
565 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
566 >    as the first action of the "Post" method and allows the handler to convert the Post
567 >    into a Cancel if that is the appropriate action on moving to a different row. This is
568 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
569 >    raised here, but it may still be more appropriate to validate a post and signal
570 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
571 >
572 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
573 >    separated list. Each library name on the list is tried in turn, in left to right
574 >    order with the first found being used as the firebird library. By default, on Linux,
575 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
576 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
577 >
578 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
579 >    then it will still attempt to access the database via the Firebird Server and will
580 >    require a username and password. If only the pathname is given, then the username
581 >    and password should be omitted and the unix file permissions are used to grant

586   1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
587      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
588      that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
589 <    correspondes to a row of the linked DataSource. Any data aware control on the
589 >    corresponds to a row of the linked DataSource. Any data aware control on the
590      replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
